                       3H2(g)+N2(g)⇌2NH3(g)

                       [H2] = 0.22M

                       [N2]    = 0.017M

                      KC = [NH3]2/[H2]3[N2]

                      1.7*102   = [NH3]2/(0.22)2(0.017)

                       [NH3]2    = 170*0.22*0.22*0.017

                      [NH3]2     = 0.139876

                      [NH3]    = 0.37
